 I have the following program below, when it runs it produces the follwing
 <?xml version="1.0"?>
 <?xml version="1.0" encoding="UTF-8"?>

 Is this a bug?
 How can I work around the issue, assuming I have to support differ libxml

 Please assume that the xml and content parameters are dynamic strings.

 #include <string.h>
 #include <libxml/tree.h>
 #include <libxml/parser.h>
 #include <libxml/xpath.h>
 #include <libxml/xpathInternals.h>

 int main(int argc, char* argv[])
    xmlDoc *doc = NULL;
    xmlNodePtr nodePI = NULL;


    doc = xmlNewDoc( xmlCharStrdup("1.0") );
    nodePI = xmlNewPI( xmlCharStrdup("xml"), xmlCharStrdup("version=\"1.0\"
    xmlAddChild( (xmlNodePtr)doc, nodePI);

    xmlSaveFile("zzzzzz.xml", doc);

    return 0;

An XML declaration might look like it, but the standard says it is not
a PI and that PIs cant be named "xml" (or any case variant of it).  So
I would say the only bug here is that xmlNewPI is not returning with
an error.
